Advancing Mission-Ready Satellite Communications

Keysight is helping accelerate the modernization of satellite ground systems through early adoption of interoperable, software-defined architectures. As one of the first organizations certified under the Digital Intermediate Frequency Interoperability standard, our engineering teams are demonstrating how open systems can meet the demands of defense-grade performance, integration speed, and operational flexibility. This certification validates the readiness of DIFI-based architectures to support secure, scalable, and resilient communications across joint and coalition environments.

The DIFI standard enables a shift from fixed analog signal chains to digital RF transport over IP networks. By packetizing IQ data and metadata, DIFI allows satellite signals to be digitized at the edge and routed through commercial Ethernet infrastructure for centralized processing. This approach reduces the need for field-deployed hardware, supports multi-orbit operations, and enables rapid reconfiguration in dynamic mission scenarios. It also lays the foundation for integrating diverse vendor technologies into a unified, mission-capable SATCOM architecture.
